To all'wkom it may concern; j 5 v 'Be itknown thatI EDMUND H- PRYCE, a subject of the King of GreatBritain, residing at the city of New Yorlgborough. of Manhattan, in the county andiState of New tYork,- have? invented eertain new' and useful "Improvements in -Signal Apparatus,- which the following is a complete specificatidn; 32 1 This inventionrelates'to improvements in signal apparatus, and has for its object to provide an apparatuswwhich is simple in construction: and operation and by means of-which .a continuous audible signalcan be produced. I u ,7 7 i 1 Further, said invention has" for its object to provide asignal apparatus the partsjxof whichmay; be readily; and easilyassembled. Further,"said inventionihasfor its object to provide a signal apparatus which iscomin appearance.

I Further, sa1d inventionhas for its :object to, provide a handroperatedsignal ,apparatus which is positiveinoperation, capable of being inexpensively made, and: which consists of; the 'minimum number of; parts so constructed andarranged as to be readily assembled. to a 'Other objects will in part be'obvious and in part be pointed ont hereinafter, I

To the attainment of the aforesaid objects and ends, my invention :consists, in the novel details'of construction, and in the combination, connection and arrangement of parts hereinafter more 'fullyf'describfed and'then pointed out in'the claims. o n v I Ina-the accompanying :drawing showing an illustrative embodiment-of the invent1on-.", 2 Figure '1 is aside elevational view'of a signal apparatusv constructed according to andfembodying the invention;
